Rare earth-chromium die alloy

Abstract

The invention relates to a rare earth-chromium die alloy. The rare earth-chromium die alloy comprises, by weight, 0.05-0.12 parts of Na, 0.5-1 part of C, 20-30 parts of Cr, 40-45 parts of rare earth, 10-15 parts of Al, 0.05-0.09 parts of Sc, 0.1-0.35 parts of K, 0.2-0.56 parts of Ti, and 0.8-1.25 parts of P. The rare earth-chromium die alloy combining many metal elements has the advantages of substantially increased strength and wear resistance, stability improvement and enterprise demand meeting.

Description

technical field [0001] The invention relates to a rare earth chromium mold alloy. Background technique [0002] With the development of science and technology, the scope of mold application is becoming more and more extensive. For the manufacture of product molds with multiple varieties, small batches or frequent updates and modifications, such as injection molds, blow molds, and compression molds, it is required to have manufacturing It has the characteristics of short cycle, low production difficulty and low cost, while the steel mold usually used in the prior art has high manufacturing cost and long cycle, and the cost of rare earth chromium alloy material is relatively low, so it is widely used in the field of manufacturing such molds . However, pure metals cannot meet the requirements such as plasticity, hardness, strength, etc., so alloying elements are usually added to improve their physical and mechanical properties. [0003] Therefore, in order to solve the above ...
